Abstract

A tamper-resistant terminator includes a connector body rotatably encapsulated within a shield. A port in the shield receives a terminal of a cable transmission system therethrough for rotational engagement with a threaded bore within the connector body. Another port in the shield provides access to a socket defined by a smooth continuous cylindrical body. The socket and the threaded bore extend in opposite directions along a longitudinal axis about which the shield is freely rotatable. A tool includes a tubular shaft having a knurled portion at the free end extends from a first handle section. A disc residing adjacent the end of the tubular shaft is carried by a shaft rotatably journaled with the tubular shaft and drivingly engaged with a second handle section. In response to relative rotation between the handle sections the disc and the knurled section of the tubular shaft move between a concentric portion for telescoping movement within the socket of the connector body and an eccentric position in for driving engagement with the socket.

Claims

1. A tool especially adapted for use in combination with a cable transmission system, said system including:

a cable terminal having an element of a rotationally engagable male/female connection pair, and

a tamper-resistant terminator having a complemental element of said connection pair and a bore coaxial with said connection pair,

and for installation and removal of said terminator with said terminal, and tool comprising;

a handle having a first portion and a second portion serially aligned;

said first portion having a tubular shaft extending therefrom;

said second portion having a first shaft extending axially through said first portion and through said tubular shaft, and having a terminal end extending beyond a terminal end of said tubular shaft;

said tubular shaft extending coaxially with a first longitudinal axis;

said second portion and first shaft being rotatable about a second longitudinal axis which is substantially parallel to and spaced from said first longitudinal axis;

a disk eccentrically attached to said terminal end of said first shaft and rotatable therewith; and

said disk being concentric in relation to said terminal end of said tubular shaft in a first position and telescopingly moveable within the bore of said terminator;

said disk being eccentric in relation to said terminal end of said tubular shaft when said first portion and said second portion are rotated relative to each other for driving engagement with the bore of said terminator.

2. The tool of claim 1 further including friction enhancing means carried by at least one of said disk and said terminal end of said tubular shaft for reinforcing the engagement with the bore of said terminator.
